Make some products stay after they are sold. It should only be possible to use with the "direct sell" option.

2 ways to code it?:
(will try todo it my self and will post here if i figgure out a fix).

1.make a option when creating offers: "make unlimited(download)" and if ticked the offer doesnt get removed when purchased. And ability to add custom download url in make offer page. The download url is sent to buyer when payment is done.

2.make a option when creating offers: "make unlimited(download)" and if ticked the buy button gets hidden so you can add custom paypal buttons in the message field instead(and linked with external script). This one may bee quicker to code.

yes and with that this can be used as a download shop too! But you need an external script to handle the downloads and backend system. It could be nice to have all "inside" phpbb so you can use ads and other phpbb-mods with this. Just an idea.. You could solve it inside phpbb with just installing sub-template mod that lets you use custom themes in selected categoies. Then use digivendor(or something) as backend. Then it will look professional. You have to make custom pages with infos aso..
But this is an fantastic mod. And auction not shop! Great work!
